To determine your bust size, wrap a measuring tape around your chest at its fullest area and round the measurement to the nearest whole number.
To calculate your waist circumference, use a tape measure. Start at the top of your hip bone, and wrap it around your waist at navel level. Ensure that the tape is not too tight and that you are not holding you’re breath while taking the measurement.
Stand sideways to a mirror and determine the fullest part of your hips. Wrap a tape measure around your widest area. The tape measure should be loose enough so that there is no skin depression. Record the measurement where the tape measure meets its end.
